STWRKY — Solanum tuberosum

Summary

PGSC0003DMG400021895 (StWRKY, also known as WRKY45 or WRKY75) on potato chromosome 5 encodes a WRKY domain-containing transcription factor that localises to the nucleus and exhibits DNA-binding, transcription factor activity, protein homodimerization, and metal- and ATP-binding. The gene is associated with regulation of nutrient responses, cell wall biogenesis, pigment and terpenoid metabolism, downregulation of photosynthesis, and fructose uptake. StWRKY is linked to numerous agronomic traits including drought tolerance and sensitivity, salt response, water use efficiency, photosynthetic and transpiration rates, starch content and digestibility, anthocyanin and chlorophyll content, plant height, stem length, rooting depth, root and shoot fresh and dry weight, and leaf size and colour. It has also been connected to phosphate acquisition, lateral root development, leaf senescence, bacterial wilt resistance, and defence responses to biotic and abiotic stresses.
